     4== 1. Introduction ==
     5
     6Current Internet protocols work well in well-connected and low latency networks; however, not all scenarios experience those characteristics. For instance, when a mobile node moves out of the communication range of a base station and back in, the connection should be re-established. Another example is deep space communication, where the RTT between Mars rovers and Earth is in the order of ten minutes, making an ordinary TCP connection to time out. Below we present a list of possible uses for DTN, but not limited to.

     22The goal of this instructions is to get the reader familiar with the concepts of DTN and to provide a stepping stone towards your DTN experiments. We provide an image  with the [https://sites.google.com/site/dtnresgroup/ DTN2 software] installed. The VMs are capable of sending and receiving bundles (very large packets, usually in the order of GB, with very large time-out).

     24==== Delay vs. Disruption ====

     26DTN is commonly referred to as Delay Tolerant Networking or Disruption Tolerant Networking, depending on the application. The figure below depicts the two concepts.
